AND GUARD THEREFOR.

Patented Jan. 311, 19 17..

Application filed February 13, 1915, Serial No. 8,077. Renewed December 20, 1916. Serial No. 138,129.

To all whom it may concern! Be it known that 1, Greece Em Moncmu,

a citizen of the United Stator residing at Lowell, in the county of liiiiddlesx and Com- 5 monwcalth of li/lassachusetts, have invented a certain new and useful Improirement in Outsole and Welt Stitching Machines and Guards Therefor, of which the following is a specification.

This invention relates to outsole andwvelt stitching machines and guards therefor};-

The object of the guard, such as hereinafter described, is to guide the worlclipon the table; to prevent the upper from projecting under the table where it is likely to be pierced and scratched by the needle an'd awl of the sewing-machine; to prevent the toecap of the shoe being stitched from catching on the worloreceiving end of the table; to avoid risks to the fingers of the Workman from the awl and needle; and to accomplish all this without fitting the sole on a last while attaching the out-sole to the welt.

In United States Patent, No. 1,112,152, granted to me September 29, 1914, I have shown, described and claimed a guard for such machines, in which patent the guard is represented as pressing against the front of the work-supporting table. In the arrangement of the guard and table shown in said patent the nearness of approach of the upper of the shoe to the needle-slot is limited by the thickness of the upper edge of the head of the guard although said upper edge is very thin in order not to materially indistance of the row of crease the minimum stitches from the shoe upper as stated 1n said patent. But in many cases, it is desirable to bring the row of stitches as near as possible to the upper. I have found that this may be done without materially thinning the head of the guard and without injuriously weakening the table by letting the head of guard into the front of the table below- ,out, attaching a new sole just as the original sole was attached and again turning the the slot which serves the top of said table beyond the ends of the g shoe. This difliculty is due to. the slightness of the projection of the sole beyond the upper in turned shoes. The guard described in said patent, in some instances, and the invention herein described in all cases, allows the edge of the old sole to reach over the needle slot far enough to allow a tap to be stitched to the old sole at a sufiicient distance from the edge of the old sole. This arrangement also assists in supporting the table which is sometimes broken by wear of the awl and needle and subsequent downward blows or pressure of the needle, awl and presser-foot.

Inthe accompanying drawing Figure 1 is a front elevation of such parts of a shoesewing machine as is necessary to the understanding of my invention, showing the guard attached to the adjustable edge-gage, and the 'worlosupporting table Fig. 2, a right-side elevation of said table and guard and adjacent parts; Fig. 3, a front elevation of the table showing the guard let into the work-receiving end of the table; Fig. 4:, a plan of the table recessed at the work-receiving end to admit the guard; Fig. 5, a plan of thetable shown in Fig. 1; Fig. 6, a front elevation of the table shown in Fig. 4; Fig. 7, a front elevation of the table shown in Figs. 1 and 5; Fig. 8, a plan of the guard adapted to be used with the table shown in Figs. 4 and 5; Fig. 9, a front elevation of a modification of the table and guard; Fig. 10, a plan of a modified guard and Fig. 11, a front elevation of a table adapted to be used with the guard shown in Fig. 10;'-Fig. 12, a front elevation of a table and guard formed integrally with each other showing also the resser-foot and edge-gage.

A indicates a part of the frame of the machine; B, the worlesupporting table; I), I as a passage for the needle and thread and awl; C, the edgegage; o, the stand which supports the edgeage and is adjustable to vary the distance of the stitches from the upper of the shoe; D, the presser-foot; d, its holder; E, the awl; all. these parts, except the table, as hereinafter explained, being of the usual construction and operation as shown in said previous patent.

In sewing the out-sole to the welt in a machine of the class to which this invention relates, the work'- is inverted and the pro-- jecting part of the welt rests upon the table avoid increasing the minimum distance of the shoe-upper from the needle and awl, that is from the row of stitches which unite the outsole and the welt,is let into the front of the table beyond the ends of the needle-slot b, the intermediate part of said upper edge 9 being cut away to avoid the necessity of thinning the comparatively weak front wall of said needle-slot and to. bear upward against. and to support; said front wall. Thefront of the head 9 and of the table B are shaped to form a smooth and practically continuous bearing surface for the shoe-upper. The incline 9 may be let into the pointed or rounded work-receiving end 12 of the table B, the upper surface of the table being recessed at 6 (Figs. 3, 4 and 6) to receive said incline, but this is not necessary as the work passes, over the incline on to the table and the. incline may be as shown in said patent and in Figs. 1, 5 and 7 of the accompanying drawin Of the modifications, Fig. 9 shows that the bearing parts g b of the head 9 and table B may be straight; Figs. 10 and 11 show, that the upper edge of the guard may be bent over backward at g to lit a corresponding groove 6 in the table; Fig. 12 shows that the guard and table may be integral with each other.

I claim as my invention:

1. In a shoe-sewing machine in combination, a work-supporting table having a necdle-slot and a recess in its front work-engaging face, and a guard extending below said table, said guard having its upper edge portion received in said recess.

2. In a shoe-sewing machine in combination, a work-supporting table having a' needle-slot and having a recess between said slot and the work-receiving end of said table, and a guard extending below said table, said guard having its upper edge portion received in said recess.

3. In a shoe-sewing machine in combination, a work-supporting table having a me dle-slot and a guard extending below said table and having its upper outer surface continuous with the front surfaceof said table.

4. In a shoe-sewing machine in combination, a work-supporting table and a guard having an incline to extend over the workreceivingend of said table, said guard and table having continuous front surfaces.

In witness whereof, I ha.ve-aflixcd my signature in presence of two witnesses.
